摘要

利用3.2—75MeV/u4个能量、2×108—12×108cm–24个剂量的O和C重离子处理3个冬小麦品种

1612研究其诱变效应。结果表明

M1代的生物损伤随剂量的增加而加大;8MeV/u能量的损伤要比高能75MeV/u时大;8MeV/u较易出现在高能75MeV/u离子和γ辐射中未见的条状叶绿素缺失损伤

此结果未见相关报导。M2代诱变效果显著

突变谱宽

有益突变（早熟、矮杆、穗形）频率明显高于γ射线

且较易诱发早抽穗性状变异。

Abstract

Dry seeds of three varieties of wheat were irradiated by 3.2—75 MeV/u 16O and 12C heavy ions with various doses. The mutagenic effects in M1 and M2 were studied. The results showed that the biological damage became higher with the increasing of the dose. For the energy of 8 MeV/u

the biological damage was higher than that for high energy (75 MeV/u). There was chlorophyll stripped deficiency in M1 generation for 8 MeV/u treatment

which was seldom found in γ -ray and high energy (75 MeV/u) heavy ions treatment and had not been reported. Wider mutational spectrum and higher useful mutation frequencies (earlier earing

dwarf stem

spike form) were observed in M2 generation by heavy ions treatment than in that by γ -ray treatment.
